Mobile Ad Hoc Network Reactive Routing Protocol to Mitigate Misbehavior Node

Abstract

Mobile ad hoc networks (MANETs) are decentralised and self-organizing computer networks in which nodes are free to come and go and are randomly placed throughout a wireless communication region. The unpredictable and ever-changing topology of a network is a direct result of its mobile nodes. MANET's adaptability and ability to self-organize make it ideal for use in industries where mistakes could have serious consequences, such as medicine, transportation, and the armed forces, where even a single miscommunication could have lethal consequences. Therefore, it's crucial that all data transfers in this sector be encrypted. Routing is a vital component of data communication networks. To put it simply, a network protocol is a set of rules for However, in a hostile environment, the cooperative nature of the nodes in a network can't be assumed, and hence route selection in MANETs fails. When intermediate nodes drop or refuse to forward packets, it causes misbehaviour at the network layer. But because to resource limitations, packets may potentially be dropped by intermediate nodes. In this paper, we examine malicious routing behaviour in a mobile ad hoc network (MANET). By minimising all potential causes of packet drop owing to limited resources, our proposed "Reactive Routing Protocol to Mitigate Misbehavior node" can reliably identify the malicious node. The proposed technique mitigates misbehaving nodes with less overhead than existing secure knowledge algorithms, as shown by analytical and simulation findings.
